If you live in Arizona, you know that our hard water can take a toll on plumbing systems, and your water heater is one of the first to feel it. Over time, minerals like calcium and magnesium settle inside the tank, forming a thick layer of sediment that reduces efficiency, water quality, and lifespan.
That’s why flushing your water heater regularly is one of the simplest and most effective ways to protect your system and save money on energy bills. But how often should you do it in Arizona’s unique water conditions?
Let’s break it down.
Inside every tank-style water heater, sediment naturally collects at the bottom over time. In Arizona’s hard water, this process happens much faster than in other parts of the country.
If left unchecked, sediment buildup can cause:
Longer heating times and higher energy bills
Rumbling or popping noises from the tank
Reduced hot water capacity
Clogged or corroded heating elements
Premature system failure
Flushing the tank clears this buildup, restoring efficiency and extending the life of your water heater.
For most homes, a general rule is to flush your water heater once a year.
However, in the Phoenix Valley and surrounding areas, where water hardness often exceeds 250 PPM, our technicians recommend:
Every 6 months for homes without a softener
Once per year for homes with a water softener or filtration system
Regular flushing removes sediment before it hardens and becomes difficult to dislodge, keeping your heater running quietly and efficiently.
If you can’t remember the last time your water heater was flushed, look out for these warning signs:
Popping or rumbling sounds while heating
Cloudy or rusty water from hot taps
Inconsistent water temperature
Decreased water pressure from hot fixtures
Water that takes longer to heat up
If you’re noticing any of these, it’s time for a professional inspection and flush.
While some homeowners attempt DIY flushing, improper draining or valve handling can damage the tank or cause leaks.
